The Respiratory Tract (RT)
The Respiratory Tract (RT)
Definition (1)
RT (respiratory system) :The organs that are involved
in breathing .
The Respiratory Tract (RT)
Definition (2)
The organs and cells that take in oxygen and get rid of carbon dioxide.
The Respiratory Tract (RT)
Definition (3)Respirations the act of breathing:inhaling (inspiration) - taking in oxygen exhaling (expiration) - giving off carbon dioxide.
The Respiratory Tract (RT)
Definition (4)
The system begins at the nasal entrance, where particles are inhalable and continues through the thoracic cavity and down into the respirable gas exchange regions of the lungs.
The Respiratory Tract (RT)
Components
1 .Nose
2 .Throat
3 .Larynx
4 .Trachea
5 .Bronchi
6 .Lungs
The Respiratory Tract (RT)
The upper respiratory
tract includes the:
• nose • nasal cavity • frontal sinuses • maxillary sinus • larynx • trachea
The Respiratory Tract (RT)
The lower respiratory tract includes the:
• lungs • bronchi • alveoli
